Sonar Bookends is an automatic index generator for a variety of file formats, including PDF files. It can make an index without doing any marking in 4 ways:
With a user-supplied list of words and phrases to be indexed.
With a list of proper nouns generated by Sonar Bookends.
With a list of words filtered by frequency.
Any combination of the above.
One file, or an entire folder of files, can be indexed at one time. Indices can be single-level or multiple-level. Sonar Bookends can sort a word/phrase list, convert it from a single-level to a multple-level list automatically, reverse first and last names, and sort both single-level or multiple-level word/phrase lists.
The index can be formatted in several ways. The index is saved as a text only file so that it can be flowed into any word processor or desktop publishing program.
OK, so you want to stamp your document. Maybe you need to give reviewers some advice about the document's status or sensitivity. This tip from author Ted Padova demonstrates how to add stamps with the Stamp Tool along with related comments.
